A new BBC documentary series will explore what life is like inside prison.

The first episode in the three-part investigative series will examine the increase in contraband getting into British prisons, how drugs are dealt to people behind bars and how the rise in technology is driving violence between inmates.

Breaking Into Prison, which will be available on BBC Three, will uncover the links in the contraband chain on both sides of the law, with filmmaker Livvy Haydock spending time with criminals who make 10 times a drug's street value by selling to prisoners.

Haydock will also learn how drones and corrupt officers can be effective means of getting contraband inside prison walls.

She said: "This film exposes the shocking levels of contraband getting into UK prisons. Hearing from those on the frontline I discover just how out of control things are."

Leila Monks, director of the film and co-founder of Antidote Productions, added: "We're really proud of this documentary as it reveals the complexities of an underground network that is hidden from view.

"Livvy is the perfect person to help navigate this world and we're glad to be championing new female talent."

Details on the other two films in the series will be announced soon.

Breaking Into Prison will be available on BBC Three apps, BBC Three on iPlayer and BBC Three YouTube from November 7.
